sata_via: Enable hotplug only on VT6421
Commit 57e5568fda ("sata_via: Implement hotplug for VT6421") adds
hotplug IRQ handler for VT6421 but enables hotplug on all chips. This
is a bug because it causes "irq xx: nobody cared" error on VT6420 when
hot-(un)plugging a drive:
[ 381.839948] irq 20: nobody cared (try booting with the "irqpoll" option)

Seems that VT6420 can do hotplug too (there's no documentation) but the
comments say that SCR register access (required for detecting hotplug
events) can cause problems on these chips.
For now, just keep hotplug disabled on anything other than VT6421.
